Like other saddles designed to keep you comfortable while you’re riding in an aggressive aero position, the Sitero relieves pressure on your perineum. A deep channel runs its entire length, and there’s an opening between the points where the rider’s sit bones contact the saddle. The Sitero has a narrower nose than other split-nose saddle options, like those from ISM, which I have sometimes had to modify to achieve the ideal position.

I found the Sitero to be effective at preventing numbness. It also didn’t cause any chafing, and there was just enough padding on the nose to let me comfortably push the pace while riding on the aero extensions. The saddle also proved comfortable when I had to sit up on longer climbs. Specialized says that its “one-size-fits-most” shape—based on its Body Geometry concept—means that most riders can find a comfortable spot by moving backwards or forwards on the saddle.

Two versions of the Sitero will hit shops in early May: the Pro model, which is black and has carbon rails ($225), and a white Expert version with titanium rails ($176). Both saddles have 7x9mm rails (which may require a special clamp on some seat posts) and come with the company’s Tri-Pod water bottle carrier and a cage, which lets you carry a bottle behind your saddle. Be aware: the stock cage is a little delicate, and you might want to consider replacing it with a more robust model.

If you don’t want to use the Tri-Pod, you can use the included rack hook, which keeps your bike in place in the transition area. This is especially helpful if you’re counting on a quick T1 to get an edge on your competition—and even more so any time you’re confronted with a crowded rack.
